LoRa
Overview
Using LoRa Easy leaf, sensor data (temperature, humidity, illumination, tilt) can be sent to a distant location and output to a PC terminal.
If there is a discrepancy between the temperature (or humidity) you want to display and the temperature (or humidity) of the 4-Sensors, perform the correction between the two points. For details, see here.

Source code
- 4-Sensors and AVR MCU library (timer interrupt) are required for writing. Please include the library beforehand. For details, see here.
- In the Arduino IDE, write the following program.
- Sending side 4-Sensors_LoRa_Tx.ino
- Receiving side LoRa_Rx_Serial_monitor.ino
Execution result
Open the serial monitor in the Arduino IDE and set the baud rate to 9600 bps to display the sensor data (temperature, humidity, illumination, and tilt).
